Application filed December '27, 1920. SerialNo. 433,409.

To all whom it may concern:

Be it known that I, CLIFTON 0. Simon, a citizen of the United States, and resident of Racine, in the county of Racine and State of \Visconsin, have invented certain new and useful Improvements in Machmes for Casing In Books; and l do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to improvements in machines for casing in books, and more particularly to a machine for assembling and gluing book fillers into their covers.

It is in general the ob ect of my invention to simplify and otherwise improve the structure of a machine of this character, particularly with reference to increasing the capacity thereof and eliminating a. great portion of manual labor generally necessary to machines of this character.

A more detailed object resides in the provision of a novel arrangement whereby "the various conveyors operate continuously in one direction instead of reciprocating, thus greatly increasing the capacity of the machine.

A still further object lies in the provision of automatic feeds for the different parts, which go to make up a completed book, thereby eliminating the necessity of operators to feed the machine manually.

lViththe above and other objects inview, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts, which will be hereinafter more particularly described and defined in the appended claims:

In the drawings Figure 1 represents a side elevation of a gluing and assembling machine, embodying the features of my invention.

Figure 2 is a planview of the machine.

Figure 3 is a sectional view, taken upon the plane indicated by the line 3-3 of Figure 1.

Figure l is an enlarged transverse sectional view, taken through the filler feeding mechanism and its associate parts, as inclicated by the line 4-4 of Figure 1.,

Figure 5 is a sectional plan view, illustrating particularly the filler retaining saddle, taken upon the plane indicated by the line :)5 of Figure 1.

to handle an inexpensive grade of books, which, due to the1r cheapness in price, must,

be turned out in large quantities at a small cost for labor. books of this character is the gluing and assembling of the fillers, which come'to the machine stitched or otherwise secured to- The preferred form of machine for. accomplishing this operation is disclosed in the accompanying drawings, in which the numeral 1 designates a frame provided with an upper bed plate 2 and cross struts 3. Extending laterally from the side of the machine area pair of supporting brackets 24 adapted to hold the book fillers F, as indicated by clotted lines in Figure 4:. Slidably mounted upon the brackets 4 is a. follower 5 provided with a lug 5 adapted to engage in any desired link of a chain 6, positi0ned cent-rally of the brackets 4: and running over the sprockets 7 and '7 carried by shafts mounted in said brackets. As best shown in Figures 4 and 5, the chain 6 is driven by means of the lever 8 and pawl 9 pivotedthereto, the pawl being adapted to engage and drive, intermittently in one direction, a ratchet wheel 10 secured tothe gear '7.

Mounted at the inner end of the supporting brackets 4 are a pair of brackets 11 that carry the groovedguides 12, in which a filler elevating block 13 is reciprocatively mount.- ed. Secured to that surface of theblock 13 adjacent the filler supporting brackets isan abutment plate 14;, against, which the fillers" are held by the follower 5, while the lower end of the plate 14 is provided with a block 15 adapted to engage and elevate a single filler, upon upward movement of the block 13. The opposite surface of the elevating block 13 is provided with a rack16.,.which is engaged by the tooth segment 17 mounted on the oscillatory shaft 18. Depending-from the block 13 is a pivoted link 19 provided with a slot 19, into which extends a pin 8' carried by the lever 8. The lower end of The final operation upon the link 19 is provided with a set screw 19" adapted to regulate the amount of movement transmitted to the lever 8 upon its idle stroke, which, in turn, regulates through the associated mechanism the distance of feed of the follower 5. The downward or working stroke of the lever 8 is obtained by a weight .20 secured to its extreme end.

. engage, during a portion of their travel, the

cam tracks 28 mounted upon the tables 21.

. Disposed between the blocks 24 and the inner the filler.

ends of the studs 25 are springs 29 adapted to normally urge the opposing sets of fingers 26 apart. WVhen the fingers 26 are carried forward upon their working stretch, the cams-28 are so positioned that the rollers 27, of the opposing fingers 26, will be engaged, thereby forcing the fingers to grip and convey the elevated filler to a predetermined point, where the rollers leave the cam track and cause the fingers to release This operation is best illustrated in Figures 3 and 60f the drawings.

Positioned within the path of travel of the filler, as it is carried forward. by the fingers 26, is a saddle 30 comprising two spaced vertical plates provided with upwardly extending portions at their lower ends, which portions are-secured to the spaced tables 21 at their adjacent edges. Mounted adjacent the forward end of the saddle and secured to one of the brackets 4 is a tapered dividing knife 32 adapted to split the filler, in order that the same will straddle the saddle as it is carried forward. In order to insure an approximate equal division of the leaves of a filler, guides 33 are positioned at the sides of the dividing knife to form a throat at the apex of th knife of approximately the same width as the filler.

Mounted at the discharge end of the machine and forming that part of a frame between the bed plate 2 and cross struts 3 is the vertical guide 33 provided with grooved ways 34, in which travel the flange blocks 35 having secured thereto carrier plates 36. The blocks 35 are attached to an endless vertical chain conveyor 36 that travels over sprockets 37 mounted upon shafts j ournalled at the upper and lower ends of the guide 33. Mounted upon the opposite sides of the sprockets 37 are flanged sectors 37 adapted to engage and form a backing for the flanged blocks 38, as they travel over the sprocket wheels. Thus it will be seen that at all times the blocks 35, which are secured to the carrier plates 36, are firmly held in proper alignment, which is most desirable during their working stretch, or that part of their travel in which they are conveying the filler from the saddle to the point of discharge.

As best shown in Figure 6, when the carrier plates travel upward, they pass through the spaced plates of the saddle 30 and engage between the leaves of the filler which has been carried forward and straddles the saddle, as indicated in dotted lines. The filler is then conveyed upwardly to a pair of spaced driven glue rollers 40 mounted upon the shafts 41 that are journalled in glue pots 42. Depending from the bed plate 2 are spaced brackets 43, in which are journalled shafts 44 that form a pivotal mounting for the glue pots 42. l/Vithin the glue pots are roll ers 45 that transmit glue to the rollers 40. Attached to arms extending from the bed plates 2, and glue pots, are contractile springs 46 adapted to form a resilient connection to hold the glue pots in their normal position, which position is regulated by means of stops 47 comprising two telescoping members, one of which is threaded and provided with an adjustable nut to limit their telescoping movement. The stops 47 are connected to the same arms projecting from the bed plates and glue pots that carry the springs 46 and enable the relative position of the glue rolls 40 to be regulated for different thicknesses of filler. This con nection Jermits the rollers 40 to move apart as the filler passes therethrough, and at the same time yieldably holds the gluing rollers in contact with the filler and insures a thorough coating of glue thereon.

Mounted on the bed plate 2 at one end of the machine is a magazine 48 adapted to hold the book covers and permit them to be fed singly to that part of the machine, where they are assembled and glued to the fillers. The magazine consists of a stationary front wall 49, a back wall 50, and the adjustable sides 51. Adjustably secured to the inner surface of the sides 51 are angle iron guides 52 having their connecting bolts secured in the slots 53. The sides 51 are also adjustable with relation to the front and back by means of their slotting connection. This permits the magazine to be adjusted to any desired cover within a certain limit. l Vithin the maximum width of a book cover, the bottom of the stationary front 49 is spaced above the table, while adjustably secured to the front wall is a plate 54 adapted to restrict this space to the desired thickness of book cover to be fed from the magazine. Mounted adjacent the underside of the bed plat are a pair of endless feed chains 54 that travel over sprockets :55. Secured to thechains 5tare spring pawls 56 that extend through the slots.57 from. the hedplate 1 2, and engage one edge of the lowermost book cover in the magazine and feed the same forward to a pair of tape conveyors '58 running over pulleys 59 and .along the top surface of the bed plate 2'. When the covers come in contact with the stops 60, which are adjustably mounted upon the bed plate, they are held in this position to receive the filler being conveyed upward upon one of the carrier plates 36.

Adjustably mounted upon the bed plate 2 by means of slotted connectionsare a pair of brackets 61, in which are pivotally mounted the links 62 that carry guide rolls 63. As the cover is engaged by the filler and fed upwardly through the guide rollers, the same cause the sides of the book to be bent downwardly over the sides of the filler, at Which point the assembledfiller and cover are engaged by a pair of pressure rollers 64 mounted u on shafts. 65 journalled inthe pivotal brac ets 66, which brackets are urged together by a spring 67 connecting their lower adjacent ends. The rollers 64 are caused to rotate, through the medium of suitable geared connections to theshaft 9%, in'the same direction and at the same speed as the travel of the carrier plates 36. The brackets 66 are mounted upon a pair of driven shafts '68 I end of the shaft 72 which is journalled in the bed plate 2 and :extends horizontally through the machine. Fastened at the sides of the bed plate 2 are brackets73, in which are journalled shafts 74 and 74, which shafts are in bevel gear connection with the shaft 72, and are provided withspiral gears 75 that mesh with gears '76 mounted on the vertical shafts 77 Splined upon the shafts 7 7 in order that they might be adjusted with the tables 21 are one set of the sprocket gears 23 that -drive the conveyors 22. The extreme lower end of one of the vertical shafts 77 is provided witha bevel gear 78 for driving the stub shaft 79, on which is mounted a crank wheel 80, connected by a link 81 to the rocker arm 82secured to-one end of the, shaft 18. Through this connecition it will beseen that oscillatory movement 'is transmitted to the shaft 18, which shaft 7 carries the tooth sector 17 for reciprocating the elevating blbck 13, causing the fillers to be fed to the conveyor 22. As shown in Figures 3 and 8,;abevel pinion 83 is mounted upon the shaft 72 for engaging and driving the stub shaft 85 journalled in one of the brackets 43. The lower end of the shaft lt) .isprovided with a spiral pinion 86 meshing with the pinions87 mounted upon the shafts 44,-which carry the rollers 45. The drive for the conveyor chains 54 is providedthrough one set of thesprocket gears 56, which -are also mounted upon the shaft 72.

Journalled in and extending transversely through the vertical guide 33 between the stretches of the conveyor chain 36 is a shaft 88, on which are m'ounted one set of rollers 59 which drive thetape conveyo-r58. The shaft 88 is extended at one side of the machine to carry a belt pulley' 89, that is connected by means of a belt 90 to the pulley 91 fast on the shaft 72. The shaft 74, through a pair of beveled gears 92, transmits power to the vertical shaft'93. which in turn is in beveled gear connection with the shaft 94%. Journalled in the vertical guide 33 and upon the shaft 9st is mounted one of the sprocket wheels 37 that carries the vertical conveyor chain 36. Secured on the shaft 9 l '-u'pon opposite sides of the sprocket wheel, 37 are beveled pinion-s 95 adapted to drive the shafts 68, upon which are mounted the brackets that carry the idler fgears through which power is transmitted tothe pressure rollers 64c journalled therein; The operation is as follows: A. number of the fillers .F are placed upon the brackets 4, after which the follower 5 is positioned thereon and engaged in the chain 6, by means of a lug 5 inserted into one of the links thereof. The'follower, together with chain 6, are-then moved-forward until the fillers abut the plate 14, as indi cated in Figure 4:, it beingunderstood that because of the ratchet feed the link chain 6 is free to be moved in that direction. Adesired number of covers B are then placed in the magazine 4:8 and power applied to the machine, which will cause the block 13 to be elevated, whereupon it engages one of the fillers, elevating it to a position where the spring fingers -26 of the conveyor 22 grip it and feed it forward,during whichoperation its leaves are divided by theftape'red knife to enable it .to straddle the saddle 30, where it is deposited wh enthe grippingfingers 26rele'ase it. The carrier plates 36, in their upward travel, pass between the spaced "plates of the saddle and pick *up the'filler, which is car- 'ried 'through' the rollers 40 that apply. 'a coat of glue to its outer surface. Concurrently,

with the above operation, the pawl 56 er the conveor chainf54"en a 'esand feeds one of thecoversfrom themagazin'e to the conveyor tapes 58 that carrylt forward until 1t 1s' en-.

gaged and held in place "byth'e adjustable stops 60, where it is properly --aligned and adapted to receive the filler being carried upward upon one of the plates 36. The assembled cover and filler then passes thru the guide rolls 63 which cause the cover to be folded downward into contact with the sides of the filler and held in contact with the same during the upward movement of the assembled book. As the book leaves the guide rolls 6?) the same is engaged by the pressure rolls 6% which cause the cover and filler to firmly adhere together.

The completed books are then removed from the carrier plates, either manually, or they can be delivered to any suitable chute or discharge, which is not shown, and forms no part of my present invention.

From the foregoing, it will be seen that a very simple andefficient machine has been devised for this particular purpose. In view of the fact that the difi'erent parts, which go to make up the completed book, travel through the machine in acontinuous and progressive movement, which movement is so timed that the parts are delivered practically simultaneously at the place of assembling, the capacity and output is increased to a maximum.
